Didn't the Morris Phrygian ever make it to the market?

Er dunno, but there was a convertable (sic) which would make it a Morris Aeolian.

notable for its airs?

FWIW I always found getting a MM (actually a Morris 1000) into first gear was easier if the car rolled backwards a touch, never stationary or forwards.

FWIW (a bit more) there is a thread in this parish about musical roads.
